How do I find reliable application security testing tools for building a secure code review process across multiple programming languages?

To find reliable application security testing tools for a secure code review process across multiple programming languages, focus on coverage, accuracy, integration, and governance rather than just feature lists.

1) Start with your requirements

Define:

• Languages/frameworks you use
• App types: web, API, mobile, cloud-native, desktop
• Testing needs:
  • SAST (static code analysis)
  • SCA (open-source dependency scanning)
  • Secrets scanning
  • IaC scanning (Terraform, Kubernetes, CloudFormation)
  • DAST (dynamic testing)
  • Container/image scanning
• CI/CD systems: GitHub Actions, GitLab, Jenkins, Azure DevOps, etc.
• Compliance goals: OWASP ASVS, PCI DSS, SOC 2, ISO 27001, etc.

2) Look for tools that support your language mix

For multi-language environments, choose tools with strong support for the languages you actually use. Common options include:

• SAST:
  • CodeQL
  • Semgrep
  • SonarQube
  • Checkmarx
  • Fortify
  • Veracode
• SCA / dependency:
  • Snyk
  • Mend
  • Dependabot
  • OWASP Dependency-Check
• Secrets:
  • Gitleaks
  • TruffleHog
• IaC / container:
  • Checkov
  • Trivy
  • Terrascan
• DAST:
  • OWASP ZAP
  • Burp Suite Enterprise

3) Evaluate reliability with a proof process

Don’t trust vendor claims alone. Test tools using a representative code sample:

• Include known vulnerabilities and safe code
• Measure:
  • True positives
  • False positives
  • False negatives
  • Time to scan
  • Ease of fixing findings
• Check whether findings are:
  • actionable
  • mapped to CWE/OWASP categories
  • traceable to exact lines and flows

A tool is usually “reliable” if it gives consistent, low-noise findings and integrates well into developer workflows.

4) Prioritize integration into the secure code review process

Your process should include:

• Pre-commit / pre-push checks for secrets and quick scans
• Pull request scanning for SAST and dependency issues
• CI gate checks for high-severity findings
• Scheduled scans for full repository and release branches
• Manual review for high-risk areas and tool edge cases

Good tools should support:

• CLI and APIs
• PR comments/annotations
• IDE plugins
• SARIF output
• ticketing integrations (Jira, Azure Boards, etc.)

5) Use a layered toolset, not one tool

No single tool covers everything well. A practical stack is:

• Semgrep or CodeQL for SAST
• Snyk or Dependabot for dependencies
• Gitleaks for secrets
• Checkov/Trivy for IaC and containers
• OWASP ZAP for DAST

6) Check vendor and community quality signals

Look at:

• Release cadence
• Documentation quality
• Language/framework coverage
• Community adoption and GitHub activity
• CVE response speed
• Support model and SLA
• Ability to tune rules and suppress findings safely

7) Build a pilot before standardizing

Run a 2–4 week pilot:

• Pick 2–3 representative repos
• Include different languages and app types
• Define success metrics:
  • % of real issues found
  • false positive rate
  • developer time required
  • CI impact
  • ease of reporting and triage

8) Make the review process sustainable

To keep secure code review effective:

• Establish severity thresholds
• Maintain suppression/exception policies
• Track recurring patterns
• Train developers on common findings
• Re-scan on every major dependency or framework change

A simple selection checklist

Choose tools that:

• Support your main languages
• Integrate with your CI/CD and code hosting platform
• Export results in standard formats
• Provide low-noise, actionable findings
• Cover SAST, SCA, secrets, IaC, and DAST as needed
• Allow tuning and suppression governance
• Have active maintenance and support
